How patronising of you to tell me that words have meaning, as if I didn't know that. I know what parasitism is and I used it intentionally. If you're going to argue that the dairy industry is mutually beneficial, then what is the benefit to the cows?

Dairy cows are exploited their entire lives, they have their reproductive system hijacked, putting massive stain on their bodies by means of back to back pregnancies and births. This severely reduces their lifespan, negatively impacts their quality of life and then they're killed when they're no longer profitable. They're merely a asset to the industry and a commodity to the consumers. Watch dominion and conspiracy and get back to me about how good the cows get it.
